NEGATIVE AND TRENT. REEL.

Application filed December at, 1922. fist-ea no. 608,947.

'business,'and the object of my improvementis to provide a device of the kind that 'is capable of carrying ina proper manner long negatives, prints, etc, so that they can be handled in the development, washing and toning baths, without being liable to become twisted, tangled and damaged in the different processes, as they are liablc to be when attempted to be handled without a reel or other device of the kind.

I attain this object by the device illustrated in the accompanying drawings, in which: I

Figure 1 is'a front elevational view of my reel, showing in broken sections a part of the reel support Fig. 2 is a cross-sectional view of Fig. 1, through 2.2; Fig. 3 is a detail view of one of the auxiliary crossbar supports taken at 33 in Fig. 1; Fig. 4 is a cross-sectional view of Fig. 5 through 4. l; Fig. '5 is a detail view in brokensect on of one of the auxiliary crossbars; Fig.. 6 is a detail view of one of .the tensionregulators,

Fig. 7 is adeta'il view of the end of one of the reel supports, and Fig. 8 is'a perspective viewjof a one-piece auxiliary crossbar.v

Similar characters of reference re'fer to similar parts throughout the several views. The side bar members a, the endicrossbars band the middle crossbar 0, constitute the frame work of my invention. The two side members a are identical in. form and structure and are each provided 'Wltll a hub memher 2 in which is firmly mounted the middle crossbar 0. This hub member 2 is provided with two recesses 2 and 2 whichv are adapted to receive the ends of'the intermediate separator bars 2 These intermediate separator bars 2 extend fronrthe one side bar a to the other side bare and serve to keep the layers of the article wound on the end i and auxiliary crossbars from resting against each other. They may also be proand support said side bar members a.

vided with-separatingjmenibers the same as "members 32'ja'nd they arelie'ld in the recesses 'Q'ahd 2P b talrsprings 2 which are mountedfi'n saidliub member 2 in recesses oiiset from said recesses 2 and 2?.

.The crossbar c is of a sufficient length to provide beariiigjp'ortioiis3 and 4, which ar'e revoliibly mounted in the uprights d which formapairt 'of 'a support member not shown in the dr'awings, but which is provided with said uprights d of a sufficient length to permitftheareel to be freely revolved thereon.

The side bar niembersa are also each providedwith a pair 'of braces 10 and 11 which "are each mountedat one end in the extending end. of the ,hub member 2 and at the othereiids on said member arespectively at g and h and they are adapted to strengthen An intermediate pair of braces y is provided, each of which extends diagonally from one to theother of the side members a, to which 'theirend'sareseciirely attached at points 12 and are securely attached to eachother at '13,,ai1da similar ofjb'r'afc es 7c are similarly attached to "the side bar members at 14 and are similarly secured toeach other at 15.

' Thesuppo-it nieiiibersdare similar inconstr ucti on as shown in'Figj. 7 and are each provided with an upper bearing member 5 ends lo'we'r bearingfinembei 6. These bearing niembersb and 6 areheld together at one end by a hinge 7 and "the iiieniber 5 is adapted to be'swung'onthe hinge 7 to engage tr release the niiddleprossbar '0 from said suppo ts (2. The member 6 is provided with a wing-bolts which isadaptedto hold the member 5 inp'lace on nieiiiber 6, and said swing bolt, 8 is provided with a wing-nut 9 which facilitates the fastening or releasing o'fthe member 5.

, Telescopically mountedin the upper end of eachof tlie'side membersa is an auxiliary crossbansuppo'rt m each of which is provided with an extended portion 16 which adapts it'foi' its said mounting in the side member a.

The auxiliary crossbar support-s m are supported by two parallel members n'and 0 which are 'firinly secured at their ends to 'ine mber p. which is also firmly mounted on said auxiliary crossbar supports m at 7*.

Said angletl'brac'e member 29 is provided at it's-angle 1 8 with a hollowed portion 19 in which is firinly "mounted the crossbar n.-

The crossbar supports m and s are each provided with a recess 21 and offset from said recess 21 there. is provided a plurality of recesses in which are placed ball springs 22. The recess 21 is adapted to receive the ends of the auxiliary crossbars 23, 24 and 25, and the pressure of the ball springs 22 hold the said auxiliary crossbars in their positions in said supports m.

On the opposite ends of the side bar members a are firmly mounted similar auxiliary crossbar support members 8 which are similar in construction and are supplied with a like number of ball springs as the cross-bar supports m, and are adapted to hold the ends of the auxiliary crossbar members 26, 27 and 28 the same as the auxiliary crossbars 23, 24 and are held as described above.

A tension regulator member t (Fig. 6) is mounted on the upper end of each of the side bar members a at 00, and the coil spring member 29 at its upper end is attached firmly to the portion 16 of the said support member m and is adapted to regulate the tension on the auxiliary cross-bars 23, 24 and 25, and 26, 27 and 28. This tension regulator member t is provided with a revolving locking member to which is revolubly mounted in the lug 30 and is adapted to be revolved therein for the purposce of looking said auxiliary crossbar supports m, or of releasing same. This member to is provided with a handle portion 31 to facilitate its revolution. As shown in'Fig. 5 the lower end crossbar b and the'member n may be provided with separating members 32 on .their bearing surfaces, which are adapted to hold the strips of negatives or prints from moving upon one another. The auxiliary crossbars are also provided with these separator members 32 for the same purpose.

The auxiliary crossbar members shown in the drawings are each composed of three horizontal rods 33, 34 and 35 and are mounted at their ends in a curved member 36.

The rod 33 has its end 37 extended sufficiently beyond the member 36 to form the bearings for mounting the auxiliary crossbars in the recesses 21 of the auxiliary crossbar supports m. This curved member 36 of each of the auxiliary crossbars is of a sufficient width to provide a space between the auxiliary crossbars when said auxiliary crossbars are placed one above the other as shown best in Fig. 2. The curved members 36 of the crossbars 25 and 26 are of the same length and the curved members of the crossbars 24 and 27 are of the same length but sufficiently longer than those of crossbars 25 and 26 to extend outwardly sufliciently each Way to provide a space between said auxiliary crossbars for the negative or prints placed thereon that will not allow the coils of prints or negatives to touch each other. Likewise, and for the same purpose, the curved member 36 on the crossbar members 23 and 28 are made longer than said member 36 on the crossbars 24 and 27.

These auxiliary crossbar members may also be made of a single piece of material as shown in Fig. 8 in which construction there is provided a plurality of parallel ridges 8 which perform the same functions as the rods 33, 34 and 35 perform, and the end portion 8 is of the same general shape as the members 36, and the bearing portions 8 perform the same function as the portions 37 of the auxiliary crossbars hereina before described.

On the extended portion 4 of the middle crossbar 0 there is provided a handle member 38 which is adapted to facilitate the revolving of the reel and for use in handling the, reel when removed from the supports (8.

In operation the auxiliary crossbarsand intermediate separator bars 2 are all removed and the film, negative or print to be worked on, is wound on the reel on the lower end crossbars b and member a between the separators 32, in single layers, and when the crossbars Z) and member n are filled the auxiliary crossbars 25 and 26 and the intermediate scparator bars 2 are placed in their respective positions in the supports m and s and the process of winding on the article is continued, and as each set of auxiliary crossbars are covered, additional auxiliary crossbars and intermediate separators are added until the entire film, negative or print is wound on the reel. In order to remove the reel from the supports (Z the wing-nuts 9 are released and the swing-bolts 8 are swung out of engagement with the members 5, when the reel may be removed.

Having thus described my invention, what I desire to secure by Letters Patent is:

1.
